浅谈冯家塔煤矿场区边坡滑坡治理工艺

H-M段边坡根据已开挖实体状况,可分为H-L段、L-M段。其中,L-M段风化岩石边坡采取下部做浆砌片石护裙,上部做锚杆铅丝网喷射混凝土,以降低下滑力、增加抗滑力,从而增加边坡的整体稳定性。H-L段土质边坡治理设计采用刷方减重与填土压脚相结合的方式,随山势整理为四级,下部做浆砌片石护裙,上部做浆砌片石护坡,并分别在10M,18M,24M高处设5M宽的平台,利用平台对边坡的反压作用,增加了边坡的稳定性。

Discussion on Fengjia Tower Coal Mine Slope Landslide Process

According to H-M segment slop＇s physical condition excavated,can be divided into H-L segment,L-M segment.The lower section of LM weathered rock slope was taken mortar and stones caring skirt,the upper was made of bolt galvanized wire sprayed concrete to reduce the sliding force,increase friction force,thereby increasing the overall stability of the slope.H-Lsegment soil side slope design uses a combination of brush aquare weight olss and filling soil to press feet,sorting for 4 grades with the landrorm,the lower is mortar and stones caring skirt,the upper is mortar and stones caring slope,and 5M wide platform was set at 10M,18M,24M,high,using counter-pressure of platform on the slope to increase the stability of the slope.
